Setting C: PID Setpoint
Supplies the PID setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PID setpoint.
PID operation to be enabled in b5-01 to use this setting. Refer to PID Setpoint Input Methods on page 143 .
Setting D: Frequency Bias
The input value of an analog input set to this function will be added to the frequency reference. This function can be used with
any frequency reference source.
Setting E: Motor Temperature
In addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient) thermistor
for motor insulation protection.
Setting F: Through Mode
When set to F, an input does not affect any drive function, but the input level can still be read out by a PLC via BACnet, P1,
N2, or MEMOBUS/Modbus communications.
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The difference of the PID feedback
input value and the differential feedback input value builds the feedback value used to calculate the PID input. Refer to PID
Feedback Input Methods on page 143 .
Setting 1F: HAND Reference
Sets the frequency reference when in HAND Mode and parameter Z1-41, HAND Speed Reference Selection, is set to 1
(Analog).
Setting 25: Secondary PI Setpoint
10 V = S3-02 (Maximum Output Frequency).
Setting 26: Secondary PI Feedback
10 V = S3-02 (Maximum Output Frequency).
u H4: Multi-Function Analog Outputs
These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive
performance.
n H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection
Sets the desired drive monitor parameter Uo-oo to output as an analog value via terminal FM and AM. Refer to U: Monitor
Parameters on page 206 for a list of all monitors. The “Analog Output Level” column indicates whether a monitor can be
used for analog output.
Example: Enter “103” for U1-03.
No. Name Setting Range Default
H4-01 Multi-Function Analog Output Terminal FM Monitor Selection 000 to 621 102
H4-04 Multi-Function Analog Output Terminal AM Monitor Selection 000 to 621 103
A setting of 031 or 000 applies no drive monitor to the analog output. With this setting, terminal functions as well as FM and
AM output levels can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).
n H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
H4-05, H4-06: Multi-Function Analog Output Terminal AM Gain and Bias
Parameters H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameters H4-03 and H4-06 set the terminal FM and AM output signal level when the value of the selected monitor
is at 0%. Both are set as a percentage, where 100% equals 10 Vdc or 20 mA analog output and 0% equals 0 V or 4 mA. The
output voltage of both terminals is limited to +/-10 Vdc.
The output signal range can be selected between 0 to +10 Vdc or -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. Figure 5.37 illustrates how gain and bias settings work.
No. Name Setting Range Default
H4-02 Multi-Function Analog Output Terminal FM Gain -999.9 to 999.9% 100.0%
H4-03 Multi-Function Analog Output Terminal FM Bias -999.9 to 999.9% 0.0%
